SPECIFICATION forming part Of Letters Patent No. 500,678, dated July 4,1893.

Application filed September 26, 1892. Serial No. 446,954. (No model.)

To ctZZ whom it may concern.-

Be it known that I, GEORGE EUGENE SURGI, a citizen of the United States,residing at New Orleans, in the parish of Orleans and State ofLouisiana, have invented certain new and useful Improvements in Pile orTimber Protectors and Preservers; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in piles, railway ties, 850., andit has for its general object to provide apile of a cheap, simple, anddurable construction,thoroughly adapted to withstand the ravages ofteredos and other insects, and the action of water.

With the foregoing end in view, the invention will be fully understoodfrom the following description and claims when taken in connection withthe accompanying drawings, in which- Figure 1, is an elevation of apile. Fig. 2, is a similar view of a pileembodying my invention. Fig. 3,is an elevation of the protective molding or casing removed from a pile.Fig. 4, is a longitudinal section taken through a pile embodying myinvention. Fig. 5,is a view showing a number of piles in position. Fig.6, is a transverse section of Fig. 2, and Fig. 7, is a similar view of amodification.

In order to impart a better understanding of my improved pile, railwaytie,&c., I will describe the manner of constructing the same which is asfollows:

I take glass, either pure or with some other substance, slag iron,aluminum or any other material capable of being fused, and afterreducing the same to a molten mass, I cast or mold it around the woodenpile or tie indicated by A, in the drawings, so as to form a casing B,as illustrated. This casting or molding of the casing B, around thepile, is highly advantageous inasmuch as when the casing is so placedupon the pile or tie it tightly embraces the same so as to render theuse of fastening devices unnecessary, and

furthermore it prevents the entry of water and destructive worms betweenthe pile and 5 casing, when the tide is high, which is an importantdesideratum.

I prefer in the practice of my invention,

before the pile is incased by theinolten glass or other substance, tosurround the same with a suitable compressible substance 0, as shown inFig. 7, which compressible substance is designed and adapted to permitof an expansion and contraction of the casingB,incidental to heat andcold without the same becoming loose upon the pile, but I do not desireto be confined to the compressible substance between the pile and casingas the use of the same is only preferable and in some cases it might bedispensed with.

In the accompanying drawings, I have shown the casing B, as coveringonly that portion of the pile which is subjected to the action of thewater, but itis obvious that if desired the entire pile or any portionthereof might be covered.

It will be seen from the foregoing description that the casing 13, maybe very quickly and easily placed upon the pile, and that when so placedit will retain its primary position without the employment of fasteningdevices.

A pile or tie constructed as herein set forth is thoroughly impregnableto the destructive action of insects and sea water, and is also verystrong, whereby it will be seen that it will last for an indefiniteperiod of time regardless of the locality where it is situated.

Having described my invention, what I claim is- 1. As a new article ofmanufacture, a pile or railway tie, embodying a wooden portion, and acasing cast or molded about the wooden portion so as to tightly embracethe same and render the use of fastening devices unnecessary,substantially as specified.

2. As a new article of manufacture, a pile or railway tie embodying awooden portion, a compressible substance surrounding the wooden portion,and a casing cast or-molded about the wooden portion and compressiblesubstance, so as to tightly embrace the same and render the use offastening devices unnecessary, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
